Here is a picture of what looks like actual CT tactical team apparently escorting non-tactical officers. Maybe this this an advance team for the Governor - just a thought. But notice the guys with the rifles. Their weapons are at the ready and they are scanning the environment. They are holding their weapons in a manner that would appear safeties are off and they are fully engaged. Compare this to the rag-tag SWAT team with weapons slung over their shoulder (hopefully with safeties on) and their non-attentive unfocused attitude.
